Constructor Details

#initialize(cookbooks, opts = {}) ⇒ CookbookUploader

Creates a new CookbookUploader.

Arguments:

  • cookbooks:

    A Chef::CookbookVersion or array of them describing the cookbook(s) to be uploaded

  • path:

    A String or Array of Strings representing the base paths to the cookbook repositories.

  • opts:

    (optional) An options Hash

Options:

  • :force indicates that the uploader should set the force option when

    uploading the cookbook. This allows frozen CookbookVersion
documents on the server to be overwritten (otherwise a 409 is
returned by the server)

  • :rest A Chef::REST object that you have configured the way you like it.

    If you don't provide this, one will be created using the values
in Chef::Config.

  • :concurrency An integer that decided how many threads will be used to

    perform concurrent uploads
